  • This paper introduces a steering-invariant constant beamwidth beamforming algorithm with Second-Order Cone Programming (SOCP) constraints. The optimizing criterion of the proposed algorithm is suppressing the designed sidelobe level utmost while keeping the mean-squared error between the designed mainlobe and the corresponding reference mainlobe on all look directions minimizing. The constrained optimizing formula can be reformed to a standard SOCP fashion and be solved with SeDuMi, an optimization toolbox. It is shown with simulation that the proposed algorithm can obtain the steering-invariant constant beamwidth beampattern effectively under the designed main-lobe direction of 60.
